Abstract
The utility model provides a negative-pressure dust suction hood which comprises a dust suction horizontal hood arranged on the outer wall of a discharge port, wherein a dust suction upper hood is arranged above the dust suction horizontal hood, a closed dust suction chamber is formed between the dust suction horizontal hood and the dust suction upper hood, a negative pressure pipe is arranged at the top of the dust suction upper hood, the upper end of the negative pressure pipe is connected with negative pressure equipment and the lower end of the negative pressure pipe is communicated with the dust suction chamber, a dust suction port is formed at the periphery of the dust suction horizontal hood and in the position corresponding to the circumference of the upper opening of a receiving trolley which is arranged below the discharge port, and the dust suction port is a 10 mm gap which is reserved between the periphery of the dust suction horizontal hood and the dust suction upper hood. The negative-pressure dust suction hood has a simple structure and practical functions. A negative pressure zone is formed in a dust spread region, so as to effectively reduce dust spread, significantly reduce the secondary pollution of dust and reduce the damage to on-site personnel.
Description
Technical field
The utility model relates to a kind of negative pressure dust shield.
Background technology
The offal that causes in all production processes of cigar mill, dust etc. are utilized negative pressure to collect the dedusting room by deduster and focus at present.Dust after the processing is fallen in the dolly that connects material through blanking port, and in this process, yellow tiny dust scatters and flies upward, and seriously jeopardizes the healthy of site operation personnel and maintenance mans, the secondary pollution environment.
The utility model content
The utility model provides a kind of negative pressure dust shield, can significantly reduce at blanking port and fall the dust that forms in the dolly that connects material.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: the negative pressure dust shield, comprise the dust suction level cover that is arranged on the blanking port outer wall, the top of dust suction level cover is provided with in the dust suction covers, form the vacuum chamber of sealing in dust suction level cover and the dust suction between the cover, the top of covering in the dust suction is provided with the negative pressure pipe, the upper end of negative pressure pipe connects negative pressure equipment, the lower end of negative pressure pipe is communicated with vacuum chamber, be provided with suction port around the dust suction level cover, the suction port position is corresponding with the peripheral position suitable for reading of the dolly that connects material of blanking port below.
Reserve the suction port in 10mm gap between covering around the described dust suction level cover and in the dust suction.
The utility model is simple in structure.The function practicality has formed a negative pressuren zone in the dust diffusion region, has reduced the diffusion of dust effectively, has reduced the secondary pollution of dust significantly, has reduced the harm to the Field Force.
Description of drawings
Fig. 1 is a cutaway view of the present utility model.
The specific embodiment
Embodiment: as shown in Figure 1, the negative pressure dust shield, comprise the dust suction level cover 3 that is arranged on blanking port 1 outer wall, the top of dust suction level cover 3 is provided with covers 2 in the dust suction, form the vacuum chamber of sealing in dust suction level cover 3 and the dust suction between the cover 2, the top of cover 2 is provided with negative pressure pipe 4 in the dust suction, the upper end of negative pressure pipe 4 connects negative pressure equipment, the lower end of negative pressure pipe 4 is communicated with vacuum chamber, be provided with suction port around the dust suction level cover 3, the suction port position is corresponding with the peripheral position suitable for reading of the dolly 5 that connects material of blanking port 1 below.Cover the suction port of reserving the 10mm gap between 2 around the dust suction level cover 3 and in the dust suction.Solid arrow is the flow direction of dust among Fig. 1, and empty arrow is the blanking direction.
Negative pressure pipe 4 inserts the negative pressure air of adjustable size joint, and the vacuum tank that forms the gap and be 10mm around negative pressure cover is as suction port.By regulating the size of negative pressure, to around the fine dusts negative suction pipe 4 that flies away, import deduster then.
Claims (2)
1. negative pressure dust shield, it is characterized in that: comprise the dust suction level cover that is arranged on the blanking port outer wall, the top of dust suction level cover is provided with in the dust suction covers, form the vacuum chamber of sealing in dust suction level cover and the dust suction between the cover, the top of covering in the dust suction is provided with the negative pressure pipe, and the upper end of negative pressure pipe connects negative pressure equipment, and the lower end of negative pressure pipe is communicated with vacuum chamber, be provided with suction port around the dust suction level cover, the suction port position is corresponding with the peripheral position suitable for reading of the dolly that connects material of blanking port below.
